' 16 Claims. (Cl. 4-217) The main objects of this invention are:

First to provide a ventilating device of improved construction for a bowl having a hinged seat.

Second, to provide a device of this character,

which constitutes a cushion for the seat in coaction with the bowl as well, as a substantially air-tight seal and an air conduit for evacuating the bowl through a series of inwardly opening apertures.

Third, to provide a device of this character including a fitting adjustably'secured to the bowl at the back ofthe seat for coaction with the conduit when the seat is down; the-cushion abutting the fitting to provide a substantially airtight seal.

Fourth, to provide a device of this character which may be embodied as an attachment to bowls of types now very extensively used.

Fifth, to provide a ventilating device which is simple and economical inits parts and very eificient in operation, and one which provides a combined air and noise seal between the seat and bowl.

- Objects relating to details and economies of my invention will appear from the description to follow. The invention is defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is illustratedin the accompanying drawing, in which:

Fig. 1 is a fragmentary perspective view of a bowl having a hinged seat, theparts being'provided with a ventilating device embodying the features of my invention.

Fig. 2. is an enlarged fragmentary section on a line corresponding to line 2--2 of Figs. 1 and 3;

Fig. 3 is a fragmentary top plan view, parts being broken away and shown in section.

v Fig. 4 is an enlarged fragmentary sectional view on a line corresponding to line 4-4 of Fig. 1.

Fig. 5 is a detail sectional view of a modification.

m the embodiment of my invention illustrated by Figs. 1 to 4, inclusive, of the drawing, numeral 1 indicates a bowl having a hinged seat 2, the

seat being hinged to the pintle or pivot rod 3- carried by the arms 4 of the bolts 5 at the rear of the bowl. A cover or closure 6 is also hingedpipe or nipple 11 and laterally extending attaching flanges 12, 12 resting on the top of bowl. The laterally extending flanges have parallel slots 13, 13 receiving the bolts 5, 5 for securing the fitting in adjusted position and assembled relation with the bowl. As best illustrated by Figs. 2 and 3, the fitting is arranged with its forward end under the pintle 3 and has a substantially fiat forwardly facing abutment 14.

v A continuous soft rubberpassage member or, strip 15 of outwardly facing channel section is disposed with its flange 16, 16 between the seat and bowl with its web portion overhanging the inner periphery of the latter. The passage member has a series of downwardly and inwardly facing'inlet openings or perforations 17 adapted to place the interior of the bowl in communication with an evacuating system. A soft rubber filler'or closure member 18 is disposed between ends spaced and arranged -to provide an opening 19 for registration with the opening 8 at the front 'of the fitting. The ends of the member 18 and the flanges at the back of the passage member are positioned to meet the abutment of the fitting when the seat is down as illustrated by Figs. 2 and 3. Thus arranged,- the chamber 9 of the fitting is placed in substantially air-tight communication with the passage 20 in the passage member 15 sothat an evacuating system connected to the outlet pipe 11 efliciently evacuates the interior ,of the bowl without leakage between the seat and bowl or between the fitting and the continuous member.

The flanges of the passage member and the filler member are secured together and to the seat by means of the nails or tacks 21. With the parts thus arranged, the seat is provided with a soft rubber cushion for coaetion with the top of the bowl, thereby providing a substantially air-' tight joint between these parts and which also acts as a muiiier.

In the modification of my invention illustrated by Fig. 5 of the drawing, the combined cushion and conduit comprises a rubber cushion strip or member 22 and a rubber passage member; or strip 23 arranged under the cushion and seat tdlprovide an inner continuous conduit or passage'24, the parts being secured to the seat by means of the nails or tacks 25 and 26. The passage strip has a plurality of inner and downwardly facing inlet openings 27 which place the conduit in communication with the interior of the bowl. Otherwise, the modification is substantially similar to that the flanges of the passage member and has its described above in connection with Figs. 1 to 4, inclusive.

From the above description of my invention, it will be apparent to those skilled in the art that I provide a ventilating device of the character and for the purpose described, which is not only simple and economical in its parts, but which is also very effective in operation and one which may be used with a standard bowl having a hinged seat without altering or modifying the standard parts thereof.

The flexible passage elements may be readily adjusted to the size or shape of the seat and bowl.

I have illustrated and described my improvements in embodiments which I have found very practical. I have not attempted to illustrate or describe other embodiments or adaptations, as it is believed this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.
